Boatmurdered

From DwarfFortressWiki

Boatmurdered was a succession game on the Something Awful forums. Its most prominent features were a constant Elephant seige, thrice-yearly floods of lava destroying the landscape (and elephants, and goblins, and dwarves, and the odd colossus), and a series of fiery tantrums which eventually depopulated the fortress.
